Neopixel Addressable RGB LED SK68XX-EC3210R

Neopixel Addressable RGB LED SK68XX-EC3210R is a miniature, digitally addressable LED designed for projects where space is at a premium. This tiny component packs a bright RGB LED and a smart control IC into a compact 3210-sized package. Hobbyists and engineers use this LED to create high-density light displays, wearable electronics, and other custom projects where standard 5050-sized LEDs are too large. The SK68XX-EC3210R gives you individual control over each LED’s color and brightness, all with a single data line from your microcontroller.

Key Features:

• Ultra-Compact Size: The 3.2mm x 1.0mm package is significantly smaller than the standard 5050 LEDs, making it perfect for miniature designs.
• Individual Addressability: You can program each LED’s color and brightness independently, allowing for complex and dynamic lighting effects.
• Full-Color Spectrum: Achieve vibrant colors with a 24-bit color depth, offering over 16 million color options.
• Single-Wire Control: A single data line from a microcontroller (like an Arduino or Raspberry Pi) is all you need to control an entire chain of these LEDs.
• High Refresh Rate: The integrated driver chip ensures smooth animations and a fast data transfer rate.
• Daisy-Chainable: Easily connect multiple LEDs in series to create strips or matrices of any length.

Technical Specifications:

• Operating Voltage: 4 V to 7 V (typical 5 V)
• LED Current: ~18.5 mA per color (R/G/B) at full brightness
• Color Depth: 24-bit (8 bits per channel)
• Data Protocol: One-wire protocol
• Data Transfer Speed: 800 Kbps
• Operating Temperature: -25 °C to +80 °C

Mechanical Specifications:

• Package Type: 3210 Surface-Mount Device (SMD)
• Pin Count: 4 pins
• Assembly: Designed for surface soldering to high-density PCBs.
• Material: LED package with integrated IC.

Dimensions:

• Length: 3.2 mm
• Width: 1.0 mm
• Height: 1.5 mm

Pinout and Wiring:

• VDD: Power supply (5V typical)
• VSS: Ground
• DIN: Data input from microcontroller
• DOUT: Data output to the next LED’s DIN pin
• Wiring Note: Connect VDD and VSS to a stable 5V power source. Wire a single microcontroller data pin to the DIN of the first LED, and connect subsequent LEDs from DOUT to DIN. Due to the small size, a steady hand or reflow soldering is recommended.
